Registry Trash Keys Finder (TrashReg) is an advanced Registry cleaning tool. The main function of RTKF is to allow the removal of unnecessary keys from the Windows Registry. Many programs leave keys in the Registry, even after programs removal using an uninstallation facility provided with the programs themselves. RTKF allows you to decide whether to delete or leave the keys found.
An additional effect (it may be the main aim for some users) of removal of these keys is the "revival" of some programs trial versions after the initial trial period has expired.
The program RTKF is not a crack but is an addition to other serious Registry cleaning software. No breach of software license agreement of the programs in use which remains are made when TrashReg executes according to the developers.
